Description
DESCRIPCIÓNDESCRIPTION
Tubo radiante con soporte trasero de tubo radiante corrugadoRadiant tube with corrugated radiant tube rear support
La presente invención se refiere a un tubo radiante con soporte trasero de tubo radiante corrugado.The present invention relates to a radiant tube with a corrugated radiant tube rear support.
Se conocen hornos para el tratamiento térmico de láminas y otros productos fabricados de acero y otros materiales, que comprenden, por ejemplo, un tubo radiante de forma variable, por ejemplo, con forma de "P", "S", "I", "doble P", "M" o "doble U".Furnaces are known for the heat treatment of sheets and other products made of steel and other materials, comprising, for example, a radiant tube of variable shape, for example, in the shape of "P", "S", "I", "double P", "M" or "double U".
Dicho tubo radiante está soportado por las paredes del horno, por un lado mediante una brida de fijación y por el otro mediante un soporte trasero de tubo radiante que descansa en una superficie de un receptáculo de horno fijado a la pared del horno.Said radiant tube is supported by the walls of the furnace, on the one hand by means of a fixing flange and on the other by a rear radiant tube support resting on a surface of a furnace receptacle fixed to the furnace wall.
La interacción entre el soporte trasero de tubo radiante y la superficie del receptáculo de horno permite compensar los movimientos del tubo radiante provocados por las variaciones de temperatura.The interaction between the rear radiant tube support and the surface of the furnace receptacle makes it possible to compensate for movements of the radiant tube caused by variations in temperature.
Las altas temperaturas que se alcanzan por el horno, como promedio entre 700 °C y 1200 °C, determinan un problema de adhesión del soporte trasero de tubo radiante a dicha superficie, con la consiguiente "adherencia" del tubo radiante, que por lo tanto se rompe.The high temperatures that are reached by the furnace, on average between 700 ° C and 1200 ° C, determine a problem of adhesion of the radiant tube rear support to said surface, with the consequent "adherence" of the radiant tube, which therefore breaks.
El documento WO-2011/044599 describe un tubo radiante con un soporte trasero de tubo radiante que descansa en una superficie de un receptáculo de horno fijado a la pared de un horno por medio de un plano deslizante reemplazable.WO-2011/044599 discloses a radiant tube with a radiant tube rear support resting on a surface of a furnace receptacle attached to a furnace wall by means of a replaceable sliding plane.
El documento US-4520789 muestra un tubo radiante con una brida que tiene una cavidad asociada de forma deslizante con un brazo tubular fijado a la pared del horno. Con el fin de limitar el sobrecalentamiento, dicho brazo tubular está recubierto con un material aislante térmico.US-4520789 shows a radiant tube with a flange having a cavity slidingly associated with a tubular arm fixed to the wall of the furnace. In order to limit overheating, said tubular arm is covered with a thermal insulating material.
El documento WO-2014072839 describe un tubo radiante con un soporte trasero de tubo radiante provisto de medios antiadherentes, tales como unos medios de laminación, o un recubrimiento que comprende un material de baja fricción, o un material tratado térmicamente a base de tungsteno o circonio de carbono, o cualquier otro material que tenga una rugosidad dada, o un material de endurecimiento.WO-2014072839 describes a radiant tube with a radiant tube rear support provided with non-stick means, such as a lamination means, or a coating comprising a low friction material, or a heat-treated material based on tungsten or zirconium carbon, or any other material that has a given roughness, or a hardening material.
El documento JP-8327263 describe un recubrimiento de bajo coeficiente de fricción a aplicar a las partes de un intercambiador de calor en contacto con las paredes de soporte de un horno con el fin de evitar fenómenos de adherencia.Document JP-8327263 describes a low friction coefficient coating to be applied to the parts of a heat exchanger in contact with the support walls of a furnace in order to avoid adhesion phenomena.
El documento US-7678465 describe un recubrimiento antiadherente que comprende óxido de circonio, para acero sujeto a altas temperaturas.US-7678465 describes a release coating comprising zirconium oxide, for steel subjected to high temperatures.
El documento WO-99/14400 describe un intercambiador de calor que comprende un recubrimiento protector que prevé circonio.WO-99/14400 describes a heat exchanger comprising a protective coating providing zirconium.
De manera desfavorable, el plano deslizante descrito en el documento WO-2011/044599 está sujeto a desgaste y, por lo tanto, debe reemplazarse con la consiguiente detención del horno, que debe enfriarse y a continuación calentarse nuevamente. Un problema similar se refiere a los medios de rodadura descritos en el documento WO-2014072839.Unfavorably, the sliding plane described in WO-2011/044599 is subject to wear and therefore must be replaced with consequent stopping of the furnace, which must be cooled down and then heated again. A similar problem concerns the rolling means described in WO-2014072839.
El documento WO-2014072839 también desvela una corrugación o fuelle o compensador adaptado para absorber al menos parte del empuje de un tubo radiante en un soporte de tubo radiante en el caso de que adhiera con el soporte de pared lateral del horno, permitiendo que el tubo radiante se sometido a una expansión, como una especie de "fuelle" independientemente de la adherencia, a lo largo de una distancia dada sin dañar el tubo radiante.Document WO-2014072839 also discloses a corrugation or bellows or compensator adapted to absorb at least part of the thrust of a radiant tube in a radiant tube support in the event that it adheres to the side wall support of the furnace, allowing the tube radiant is subjected to expansion, as a kind of "bellows" regardless of adhesion, over a given distance without damaging the radiant tube.
En el otro, se realiza un amplio uso de revestimientos de soporte de tubo radiante, que en todos los casos implican un trabajo complementario de aplicación en el soporte trasero de tubo radiante y un gasto adicional de investigación para encontrar el recubrimiento adecuado, que está, en todos los casos, sujeto a desgaste después de un número dado de ciclos de trabajo.In the other, extensive use is made of radiant tube support coatings, which in all cases involve additional work of application on the radiant tube rear support and an additional expense of research to find the right coating, which is, in all cases, subject to wear after a given number of duty cycles.

la figura 10 muestra una vista en planta superior de un tubo radiante en forma de "doble U".Figure 10 shows a top plan view of a "double U" shaped radiant tube.
Un tubo radiante 1 para hornos para el tratamiento térmico de láminas y otros productos de acero u otro material tiene una forma de "doble P" que prevé un conducto central 2 en comunicación con dos conductos laterales 3 por medio de dos empalmes 4, 5 (figuras 1 - 3).A radiant tube 1 for furnaces for the heat treatment of sheets and other products made of steel or other material has a "double P" shape that provides a central duct 2 in communication with two lateral ducts 3 by means of two joints 4, 5 ( Figures 1-3).
El primer empalme 4 se coloca en un primer extremo del tubo radiante 1 y se fija a una pared lateral (no mostrada en las figuras) del horno por medio de una brida 6 que permite que el fluido caliente de calentamiento entre/salga del tubo radiante 1.The first fitting 4 is placed at a first end of the radiant tube 1 and is fixed to a side wall (not shown in the figures) of the furnace by means of a flange 6 that allows the hot heating fluid to enter / exit the radiant tube 1.
Un soporte trasero de tubo radiante 7, adecuado para descansar en una superficie 81 de un receptáculo de horno 8 fijada a una segunda pared lateral del horno, se fija externamente en el segundo empalme 5 (figura 4).A radiant tube rear support 7, suitable to rest on a surface 81 of a furnace receptacle 8 fixed to a second side wall of the furnace, is externally fixed at the second joint 5 (Figure 4).
El soporte trasero de tubo radiante 7 tiene una superficie exterior corrugada 71, es decir, que se ha sometido a una operación de corrugación.The radiant tube rear support 7 has a corrugated outer surface 71, that is, it has been subjected to a corrugation operation.
Dicha superficie exterior 71 tiene una serie alterna de salientes 72 y rebajes 73 en secuencia a lo largo de la dirección de un eje deslizante L de dicho soporte trasero de tubo radiante 7, dicho eje L coincide con el eje del soporte trasero de tubo radiante tubular 7 y es ortogonal con respecto a dicha pared lateral del horno. En particular, dicho eje L representa la dirección de deslizamiento prevalente del soporte trasero de tubo radiante 7 en la superficie 81 del receptáculo de horno 8, pudiendo el soporte trasero de tubo radiante 7 deslizarse a lo largo de otras direcciones, aunque estas son, en todos los casos, secundarias con respecto a la del eje L.Said outer surface 71 has an alternating series of projections 72 and recesses 73 in sequence along the direction of a sliding axis L of said radiant tube rear support 7, said axis L coincides with the axis of the tubular radiant tube rear support 7 and is orthogonal with respect to said side wall of the oven. In particular, said axis L represents the prevailing sliding direction of the rear radiant tube support 7 on the surface 81 of the furnace receptacle 8, the rear radiant tube support 7 being able to slide along other directions, although these are, in all cases, secondary with respect to the axis L.
Preferentemente, el paso de corrugación (es decir, la distancia entre dos salientes consecutivos 72 o dos rebajes consecutivos 73) está comprendido entre 35 mm y 45 mm, y la profundidad de los rebajes 73 (la distancia entre el máximo 721 de un saliente 72 y la parte inferior 731 de un el rebaje 73) es mayor o igual que 1 mm, preferentemente comprendida entre 2,5 mm y 3,5 mm.Preferably, the corrugation pitch (that is, the distance between two consecutive projections 72 or two consecutive recesses 73) is between 35 mm and 45 mm, and the depth of the recesses 73 (the distance between the maximum 721 of a projection 72 and the lower part 731 of a recess 73) is greater than or equal to 1 mm, preferably between 2.5 mm and 3.5 mm.
Incluso más preferentemente, el paso de corrugación (la distancia entre dos salientes consecutivos 72 o dos rebajes consecutivos 73) es de aproximadamente 40 mm, y la profundidad de los rebajes 73 (la distancia entre el máximo 721 de un saliente 72 y la parte inferior 731 de un rebaje 73) es aproximadamente 3 mm.Even more preferably, the corrugation pitch (the distance between two consecutive protrusions 72 or two consecutive recesses 73) is approximately 40 mm, and the depth of the recesses 73 (the distance between the maximum 721 of a protrusion 72 and the bottom 731 of a recess 73) is approximately 3mm.
Preferentemente, la longitud del soporte trasero de tubo radiante 7 está comprendida entre 250 mm y 350 mm. Incluso más preferentemente, el soporte trasero de tubo radiante 7 es de aproximadamente 300 mm de largo.Preferably, the length of the radiant tube rear support 7 is between 250 mm and 350 mm. Even more preferably, the radiant tube rear support 7 is approximately 300mm long.
Fundamentalmente importante es la profundidad de los rebajes 73, que debe ser mayor o igual aque 1 mm para permitir que el soporte trasero de tubo radiante 7 descanse en la superficie 81 del receptáculo de horno 8 solo en los puntos máximos 721 de los salientes 72: en consecuencia, el contacto es puntiforme, evitando de este modo los fenómenos de adherencia. La presencia de la serie alterna de salientes 72 y rebajes 73 significa que el soporte trasero de tubo radiante 7 puede deslizarse, sin adherencia, en dicha superficie 81 del receptáculo de horno 8, y en particular que dicho soporte trasero de tubo radiante 7 puede deslizarse predominantemente a lo largo de la dirección del eje deslizante L. Una profundidad menor no evitaría la adherencia a temperaturas muy altas. Fundamentally important is the depth of the recesses 73, which must be greater than or equal to 1 mm to allow the radiant tube rear support 7 to rest on the surface 81 of the furnace receptacle 8 only at the maximum points 721 of the protrusions 72: consequently, the contact is punctiform, thus avoiding adhesion phenomena. The presence of the alternating series of projections 72 and recesses 73 means that the rear radiant tube support 7 can slide, without sticking, on said surface 81 of the furnace receptacle 8, and in particular that said rear radiant tube support 7 can slide predominantly along the direction of the sliding shaft L. A shallower depth would not prevent adhesion at very high temperatures.
Ventajosamente, La profundidad de los rebajes permite tener un espacio suficiente para contener posibles escorias dentro del horno. Asimismo, el soporte trasero de tubo radiante 7 prevé unos agujeros pasantes 75 para permitir la liberación de un posible sobrecalentamiento que de otro modo podría generarse en una cámara cerrada; preferentemente, el soporte trasero de tubo radiante 7 comprende cuatro agujeros pasantes 75 a 90°.Advantageously, the depth of the recesses allows sufficient space to contain possible slag inside the furnace. Likewise, the rear radiant tube support 7 provides through holes 75 to allow the release of a possible overheating that could otherwise be generated in a closed chamber; preferably, the radiant tube rear support 7 comprises four through holes 75 to 90 °.
En la realización mostrada anteriormente, el soporte trasero de tubo radiante 7 no tiene ningún recubrimiento: solo se corruga durante la etapa de fabricación del tubo radiante 1.In the embodiment shown above, the radiant tube rear support 7 does not have any coating: it is only corrugated during the radiant tube 1 manufacturing step.
Para limitar el sobrecalentamiento del soporte trasero de tubo radiante 7, puede recubrirse con una sustancia aislante térmica que comprende óxido de circonio (en porcentaje en peso superior al 90 %) y óxido de itrio (en porcentaje en peso inferior al 10 %).To limit overheating of the radiant tube rear support 7, it can be coated with a thermal insulating substance comprising zirconium oxide (in percentage by weight greater than 90%) and yttrium oxide (in percentage by weight less than 10%).
Dicha sustancia crea una barrera térmica entre el soporte trasero de tubo radiante 7 y la superficie 81 del receptáculo de horno 8.Said substance creates a thermal barrier between the radiant tube rear support 7 and the surface 81 of the furnace receptacle 8.
En una realización, dicha sustancia comprende ZrO2 al 92 % en peso e Y2O3 al 8 % en peso.In one embodiment, said substance comprises 92% by weight ZrO2 and 8% by weight Y2O3.
Ventajosamente, dicha sustancia tiene un porcentaje de porosidad (en peso) comprendido entre 10 y 15, una microdureza (HV300) comprendida entre 500 y 600, una capacidad de unión superior a 8 MPa y confiere una rugosidad (Ra) comprendida entre 7 y 8 pm a la superficie pulverizada.Advantageously, said substance has a porosity percentage (by weight) comprised between 10 and 15, a microhardness (HV300) comprised between 500 and 600, a binding capacity greater than 8 MPa and confers a roughness (Ra) comprised between 7 and 8 pm to the sprayed surface.
Asimismo, dicha sustancia aumenta la resistencia a la corrosión del soporte trasero de tubo radiante 7 a altas temperaturas.Also, said substance increases the corrosion resistance of the radiant tube rear support 7 at high temperatures.
Dos aletas de refuerzo 10, montadas oblicuamente con respecto al eje del soporte trasero de tubo radiante 7, se proporcionan para mejorar la solidez del soporte trasero de tubo radiante 7.Two reinforcing fins 10, mounted obliquely with respect to the axis of the radiant tube rear support 7, are provided to improve the solidity of the radiant tube rear support 7.
Las figuras 6-10 muestran unas realizaciones adicionales del tubo radiante 1 de acuerdo conla invención, en forma de "P", "S", "I", "M" y "doble U", con uno o más soportes traseros de tubo radiante 7 como se describe en las reivindicaciones.Figures 6-10 show additional embodiments of the radiant tube 1 according to the invention, in the form of "P", "S", "I", "M" and "double U", with one or more rear tube supports radiant 7 as described in the claims.
El soporte trasero de tubo radiante 7 puede tener una forma diferente: puede tener una sección no circular, por ejemplo, una sección cuadrada o triangular, o ser plana. The radiant tube rear support 7 may have a different shape: it may have a non-circular section, for example a square or triangular section, or it may be flat.
